I'm a Guardian, had no problems at all. I used Kira, kept em whenever possible in a "stunlock" and timed my "defensive cooldowns". if it got a bit tight popped a medpac. done as 34 if i remember right, possibly 33. key to most fights is to watch out if you can interrupt something or stun it. when somethign does stuff on the floor it also may announce something to move from should you be unable to interrupt. that goes for almost all mmo's i ever played. if it can be interrupted, do it. if you cant interrupt, move. if its aimed, go hide (break Line of Sight). Just don't stand there spam 2 buttons and expect it to fall over, how fun would that be
